BUNG FOR BARRELS.

SPECIFICATION forming part of Letters Patent No. 506,334, dated October 10, 1893.

Applicationfiled June 23,1 93. smart. 478.566. (Nomodeld To all whom it may concern:

Be it known that we, FRANK OTTO and OTTO REINAOHER, both of New York city, New York, have invented an Improved Bung for Barrels, of which the following is a specification.

This invention relates to a hung for the spigot opening of a barrel containing beer,

ale or other liquid under pressure.

The object of the invention is to provide a bung which need not be removed while tapping, which can be opened or closed by revolving the spigot and which prevents the spigot from being driven out by the pressure of the inclosed liquid.

In the accompanying drawings: Figure 1 is a longitudinal section of ourimproved bung showing it open. Fig. 2 is a similar section showing it closed. Fig. 3 is a front view of the bung; Fig. 4 a rear view with the back plate removed. Fig. 5 is a side view. Fig 6 is a side elevation of the rear end of the spigot and Fig. 7 a perspective view of revolving plate 0. a

The letter A, represents the body of the bung made of annular form and provided with an exterior thread which is adapted to engage the threaded spigot'opening of a barrel D. The central opening a, of the bung which is adapted to receive the end of the spigot B, is enlarged at its rear end to form a chamber a. The wall a of this chamber is provided with a slot a (Fig. 5) which constitutes an outlet opening for the ale, beeror other liquid. In order to control the opening, there is placed within the chamber a, and against wall a a sliding cover b, which is curved to conform to the shape of the wall Fig. 3. This cover is operated by means of a revoluble annular plate 0, having 'two forwardly projecting lugs c, that enters the opening ct, and two rearwardly projecting lugs 0 adapted to engage the ends of the sliding cover .1). The lugs 0 should preferably be placed at such a distance apart, that the plate 0, mustbe revolved to a slight extent before the lugs will engage the cover. A spring 01, held in place by pin 0 of plate 0, and bearing with its free ends against the cover I), always holds the latter tightly against the opening a when the latter is closed, to prevent leakage.

The inner end of the spigot B, is provided with notches B, to constitute a key. These notches are adapted to engage the lugs 0, when the spigot is introduced into the bung. In order to tap the keg, the spigot is introduced and turned to the right, to revolve plate 0, and by it cover I), so that the latter clears opening a By turning the spigot in the opposite direction, the opening a is of course, closed.

At the rear, the chamber a, is closed by a plate e, while at the front the bung is provided with an annular plate f. This plate is provided with a flange f, that extends over half the edge of opening a, so that in efiect the bung is here partly undercut.

The spigot B, has a shoulder B that extends around one half its circumference and a lug or stop B at the end of such shoulder. When introducing the spigot into the bung, it is so held that the shoulder B clears the flange f, and then the first slight revolution of the spigot will'cause its shoulder to pass under the flange f, so that the spigot is locked in place and cannot be driven out by the pressure of the liquid contained in the barrel. This locking of the spigot takes place before the lug 0 will have moved the cover I), and consequently before any liquid is admitted to thebung. Thus when pressure is exerted upon the spigot, the latter is already securely locked in place, an advantage which is of considerable importance, especially when tapping ale, which is under a Very great pressure. The stop B strikes the edges of the flange f, when'the bung is completely opened or closed and thus limits the revolution of the spigot.

In order to keep the opening (1 always free and clear of pitch or other impurities, we attach to the cover I), a scraper b, which engages such openingand passes through the same from end to end at each motion of the cover.

To obtain a tight joint, a washer g, may be placed within a groove of the bung,- to embrace the spigot.

It will be seen, that our improved bung is a permanent fixture of the barrel and can be used for an indefinite length of time. It greatly facilitates the tapping operation and prevents accidents, by locking the spigot be fore the latter is subjected to pressure.

That We claim is 1. The combination of an anular bung having a lateral inlet opening 65*, with a valvelnoving plate, projecting partly into the bore of the bung so as to be engaged by the spigot, and with a valve whi h is operated by the plate, substantially as specified.

2. The combination of an annular bung with a revoluble plate having forwardly projecting lugs 0, adapted to be engaged by the IS spigot and rearwardly projecting lugs 0 and with a cover I), engaged by the lugs 0 substantially as specified.

3. The combination of an annular bung, havinga lateral inlet opening, with a revolu= 2o ble plate, and with a cover operated thereby and having a scraper adapted to engage said opening, substantially as specified.
